Example of mounting with protection pockets (recommended above DN 25)
When fitting a
cooling energy
or
combined heat/cooling energy meter
, make
sure the black cover on the measuring tube points to the side or downward to
prevent condensation. The protection pockets should also be fitted to the side or
should point downward. The processor unit must be mounted away from the flow
measuring section (e.g. on the wall). Make sure that condensation cannot run
along the connected cables, entering the processor unit (forming a loop down-
ward).

The ambient temperature of the processor unit must not exeed 55 °C. Avoid direct
sunlight.
When fitting the unit, ensure that water cannot enter during operation.
For water temperatures between 10 °C and 90 °C,
the processor unit may be left
on the flow measuring section or can be fitted to the wall (detached mounting).
For water temperatures above 90 °C or below 10 °C
,
the processor must be
secured to the wall (split mounting).
To fit the processor unit to the wall, remove it from the flow measuring section and
undo the screws of the adapter plate. The latter must then be secured to the wall
so that the processor unit can be replaced on the adapter plate, snapping into
place.
